Occasional updates can be done anytime you want, even when the product is configured to automatically update the database:

- Open BitDefender and click Update.
- Click Update now to start the update process.

If the option Prompt sooner downloading updates was selected in the Settings, and when updates are accessible, a list of the updates available for download is shown. Pick the desired utility to install and then click on "Details" in order to see the file download details.
